Well deep/hard is different I guess; I use it, day and night, for things I find boring. Boilerplate coding (which now is basically everything that's not pure business logic / logic / etc), corporate docs, reports etc. Everything I don't want to do is done by AI now. It's great. Outside work I use it for absolutely nothing though; I am writing a book, framework and database; that's all manual work (and I don't AI is good at any of those (yet)).
